Without carbohydrates it will not provide the best energy source this will deplete protein supplies needed for growth & repair of body tissues. Proteins ~a nutrient found in every cell in your body Protein is made of amino acids needed for growth, maitnence & repair of body tissue Without adequate protein growth is stunted. Food sources are meat, poultry, fish, milk, cheese, & eggs. FATS are concentrated sources of food and energy Saturated fats- solid at room temperature Ex: meat, and butter, foods that come from aimal sources

Unsaturated fats- most often liquid at room temperature Ex: corn oil, and soy bean oil, foods that come from plant sources Fats are needed to help the body distribute and use citamins, also suppy essentioal fatty acids wich are needed for normal growth. Problems that arise with to much fat in your diet.
